xmerl_xsd can't find schema

[Matti Oinas]

Hi

I'm trying to validate XML using XML schema but
xmer_xsd:process_schema can't find schema in any other folder than the
current pwd().

>xmerl_xsd:process_schema("../include/user.xsd").
{error,enoent}

if I copy the user.xsd file into the folder returned by pwd() which
happens to be src and modify the path to point to that copy the
everything works just fine.

>xmerl_xsd:process_schema("user.xsd").
{ok,{xsd_state,"user.xsd",......

xmerl_scan can find the file in both folders

>xmerl_scan:file("../include/user.xsd").
{{xmlElement,'xs:schema','xs:schema',....
>xmerl_scan:file("user.xsd").
{{xmlElement,'xs:schema','xs:schema',....

It seems to be a bug or then I'm missing some point.

I'm using erlang from arch(32 bit) linux repositories.

It sounds like a big. xmerl_xsd for some reason will mess up your path.

I think this patch should solve your problem

Hi Matti,
I looked through the xmerl_xsd code and it is a bug in process_schema.
I must just check so the calls from xmerl_scan to xmerl_xsd when validating
an xml file works ok with the change.

A workaround while waiting for the fix is:

xmerl_xsd:process_schema(<xsd file without path>, [{xsdbase, <path to schema dir>}]).

There is just one thing that I wonder about, the only case that works for me when I use a path
to the schema is ../dir/file.xsd because ../dir/../dir/file.xsd is the same place.


Regards Lars
